Magnetic and magnetostrictive properties in heat-treated Fe-Co wire for smart material/ device

The use of inverse magnetostriction effect is a possible approach for the applications of actuator, sensor and energy harvester. A strong textured Fe100-xCox (x = 70 mol%) magnetostrictive alloys have been studies as a new smart material. The design of microstructure plays important roles in perform...
